FAN53745 Description
The FAN53745 is a low quiescent current step−down DC/DC converter that delivers a regulated output voltage from an input supply of 2.3 V to 5.5 V. The bination of built−in power transistors, synchronous rectification, and a tiny solution size make the device ideal for portable applications. The converter normally operates in PWM Mode at a typical fixed−frequency of 3.33 MHz.
